Stemmer Imaging is supplying the 2/3-inch format Prosilica GX1920 from Allied Vision Technologies (AVT). The camera provides near infrared sensitivity and low light imaging performance in HD format, along with the 240MB/s data transmission capability of the GX series of dual GigE Vision cameras. This outstanding light response in both the infrared and visible regions of the spectrum is due to the Sony ICX674 CCD sensor with ExView HAD technology.
Available in monochrome and colour versions with 1,936 x 1,456 pixel (2.82 Megapixel) resolution and operating at 40fps, the EXview HAD CCD technology provides low noise, anti-blooming and excellent image quality, as well as near infrared and low light imaging capabilities. This versatile imaging device can be used in a wide range of applications from night-time surveillance, to industrial vision and factory automation systems and scientific measurement. In addition, it can contribute to automotive safety in car-mounted cameras as well as intelligent transport systems.
As with other Prosilica GX cameras, the GX1920 provides an outstanding sustained maximum data rate of 240MB/s over conventional Cat5e cables up to 100 metres long by using two Gigabit Ethernet ports configured as a Link Aggregation Group. This configuration allows the use of two cables to double the traditional GigE vision data transmission rate, or a single cable for data transmission at 120MB/s.
In addition to its speed, resolution and sensitivity, the GX1920 offers a host of smart features to further enhance its imaging versatility. These include: auto exposure, gain and white balance; flexible binning; region of interest readout; StreamBytesPerSecond for easy bandwidth control; asynchronous external trigger and sync I/O; global shutter; recorder and multi-frame acquisition modes; three-axis motorised lens control and video-type auto-iris.
